Semi-commercial remortgages. Plan your next chapter.

An approaching fixed-rate expiry, a change in ownership or a new investment can prompt a review. Look at the full cost of changing finance before focusing on a new rate.

Start with the mortgage you have

Request the outstanding balance, repayment basis, current rate and the date any fixed period ends. Check early repayment charges, exit fees and the process for obtaining a redemption statement. An apparently cheaper new rate may not offset the cost of moving.

If an existing lender offers a product change, compare it with refinancing on a like-for-like basis. Include fees, interest over the same period and the debt remaining at the end.

Separate refinancing from releasing capital

Replacing the current balance and increasing borrowing are different requests. For capital raising, set out how the additional money will be used and whether any other borrowing is involved. Do not assume every lender accepts the same purpose.

Available equity does not automatically translate into a larger mortgage. The valuation and acceptable income must also support the loan. Retained capital, security and repayments need to make sense together.

Refresh the property information

Leases and occupancy may have changed since the original mortgage. Prepare a current rent schedule and flag vacant units, tenant break clauses, arrears, lease expiries and any change in the building’s use.

  • Current mortgage statement and redemption costs.
  • Rent schedule and copies of current leases.
  • Details of completed or planned building works.
  • Amount required and a clear capital-raising purpose.
  • Company and ownership changes since the last loan.

Allow time for a proper comparison

Start gathering information ahead of an expiry or deadline. A new lender may require fresh valuation and legal work. We can discuss non-regulated requirements; regulated funding must be referred to an FCA-regulated counterparty.

Why remortgage a semi-commercial property?

A semi-commercial remortgage replaces borrowing secured against a mixed-use property. You may be approaching the end of a fixed rate, reviewing the repayment structure or considering capital raising. Begin with the purpose and the current position rather than a headline interest rate. The cost of leaving an existing mortgage can materially affect whether a new proposal makes sense.

Request an up-to-date mortgage statement and check when any early repayment charge ends. A statement balance is useful for planning, but the amount needed to redeem a loan on a particular date can include accrued interest and fees. Your solicitor will obtain the appropriate redemption information during a transaction. Do not treat a balance quoted months earlier as a guaranteed completion figure.

How much equity is actually available to release?

Equity is the difference between property value and secured debt; it is not automatically the amount a lender will release. A proposed mortgage is also constrained by acceptable loan-to-value, rental income or business performance, property criteria and the lender’s assessment of the borrower. A higher valuation does not by itself demonstrate affordable repayments.

Suppose a hypothetical building is valued at £800,000 and the proposed replacement loan is £480,000. If the amount required to redeem the existing borrowing is £360,000, the gross difference is £120,000. Deduct any fees and other completion costs funded from that amount to work out the net cash released. The calculation does not establish that a £480,000 loan is available.

What changes since the last mortgage matter?

Refresh the rent roll rather than reusing the schedule from the last application. A tenant may have exercised a break clause, a flat may be empty, or the commercial premises may have changed use. Arrears and rent concessions can affect the difference between rent in the lease and cash actually received. Identify those changes before comparing finance options.

Tell us about alterations, new leases, title changes and additional secured borrowing. If you now live in part of the building, or intend to do so, raise this at the outset. The regulatory position is assessed on the relevant facts; it does not follow automatically from the label on your old mortgage or the product used by a previous owner.

Should you compare a remortgage with keeping the existing loan?

Compare any available retention proposal and a new lender proposal over the same period, using the same starting debt. Record arrangement fees, valuation and legal costs, interest, early repayment charges and the balance remaining at the end. A lower monthly payment caused by moving from capital repayment to interest-only does not mean the debt has become cheaper overall.

Flexibility also has a cost and a value. If you plan to sell a flat, restructure a title or dispose of the whole building, ask how the proposed security and early repayment terms interact with that plan. A partial release of security requires the lender’s agreement; it should not be assumed simply because an estate agent believes one unit could be sold separately.

How should you describe the use of released capital?

Set out exactly what the funds are for: property improvements, another purchase, restructuring debt or a business purpose. Explain the timing and any money that must remain available as working capital. Where borrowing will fund works, distinguish maintenance of an occupied investment from development that changes the use or makes the building temporarily unlettable.

Keep projected rent separate from current rental income. A remortgage secured on today’s building and finance for a future completed project are different proposals. We discuss non-regulated requirements, and regulated funding is referred to an FCA-regulated counterparty. An initial conversation is not a commitment by any lender to refinance your existing debt.

Common questions

Are semi-commercial remortgages available for mixed-use properties?

Commercial mortgage lenders consider their own criteria for residential and commercial property combinations. Explain the current leases, rent, property condition and intended use. Your previous mortgage does not establish that the same loan terms or lender category will apply to a new application.

How should commercial mortgage rates be compared?

Use the same loan amount, term and repayment basis. Compare arrangement fees and exit charges as well as interest rates, and understand any fixed or variable period. A lower opening payment is not a complete cost comparison, particularly if repayment changes to interest-only.

Can limited companies release capital?

Capital raising depends on the property value, acceptable income, existing debt, purpose and borrower assessment. Limited companies should explain ownership, accounts, connected tenants and use of funds. Equity in commercial properties is not automatically cash available to withdraw.

Does affordability depend only on rent?

Rental income matters, but the lender also considers its own criteria and the circumstances of the property and borrower. Trading businesses and property investments can require different evidence. Credit commitments, vacancies and operating costs should be described accurately.

Can a remortgage replace bridging finance?

Potentially, subject to assessment of the completed property and borrower. Do not assume a future semi-commercial mortgage will repay a bridge merely because it is the planned exit. The long-term lender considers the position at the time, including value, rent, condition and legal security.

Will a business owner need regulated finance?

Owning or occupying commercial premises does not settle the position where residential accommodation is involved. Explain personal or family occupation. We are not FCA regulated and only deal with non-regulated finance; regulated requirements are referred to an FCA-regulated counterparty.
